|aFollows both the development and disappearance of water power systems froam the first undershot water wheels to the massive overshot wheel that powered the first factories of the Industrial Revolution. Describes today's main power sources, fossil fuels and nuclear energy, and then explains why environmental pressures have led to the wide scale re-introduction of the water turbine, the descendent of the water wheel. Hydro-electric power as an energy source is also discussed along with the difficulties involved in its use.
